Soviet Space Probe to Fall to Earth 50 Years After Baikonur Launch
In 1972, the Soviet Union launched a Venus-bound lander probe called Cosmos 482 from the Baikonur Cosmodrome in Kazakhstan, which was then a Soviet republic. The probe, which never got out of Earth’s orbit, is expected to re-enter Earth’s atmosphere in a week or so.
“Because the probe was designed to withstand entry into the Venus atmosphere, it is possible the probe (or parts of it) will survive reentry at Earth and reach the surface,” U.S. space agency NASA said on Friday.
“It is thought that a malfunction resulted in an engine burn which did not achieve sufficient velocity for the Venus transfer and left the payload in this elliptical Earth orbit. The lander probe orbit has been decaying over time and it is expected to reenter Earth’s atmosphere around 10 May 2025,” NASA said.
Right now, it’s hard to say where the lander will make its return. It’s possible that the spacecraft, or chunks of it, could survive reentry through the Earth’s atmosphere instead of burning up. After all, it has a titanium protective shell originally designed to get through the extreme atmosphere of Venus, which has the hottest surface of any planet in the solar system.
Dr. Marco Langbroek, a scientist based in the Netherlands, said on the SatTrackCam Leiden (b)log that he doesn’t think the lander’s parachute deployment system will work during the “uncontrolled” reentry.
“There are many uncertain factors in this though, including that this will be a long shallow reentry trajectory, and the age of the object,” Langbroek said. “The risks involved are not particularly high, but not zero: with a mass of just under 500 kg and 1-meter size, risks are similar to that of a meteorite impact.”
Today, Russia operates the Baikonur Cosmodrome, which retains a popular allure for its role in early space exploration and is still a vital part of the Russian space program.
On April 20, one NASA astronaut and two Russian cosmonauts made a parachute-supported landing on the steppes of Kazakhstan after a journey back to Earth from the International Space Station. The three men had launched from Baikonur and docked at the station on Sept. 11 last year, spending 220 days in space on that trip.
